Marshall E Rinker Sr Foundation Inc

Between its 2021–2024 filings, Marshall E Rinker Sr Foundation Inc made 57 grants to Florida organizations totaling $4,497,000 — median $50,000. Here is what they actually funded, from their IRS 990-PF filings. A note on dates: 990-PF filings become public one to two years after the fiscal year they cover, so 2024 is the newest year on public record — giving patterns persist, but always confirm current priorities with the funder.

Winnability verdict

Watch Our reading as of October 11, 2026, from filings through 2024.

  • Their filings don't publish an application route. That usually means relationships come first: start with the organizations they already fund, and watch for a stated process in their next filing.
  • A real pattern, not a one-off: 17 grants in education & literacy on their Florida record ($717,000).
  • Size the ask from their record: median grant $50,000, largest $270,000.

Deadline: No application deadline appears in the filings we have — confirm timing with the funder before planning a submission.

The verdict is our judgment from public filings — the funder’s own process statements are quoted where they exist, and funders make their own decisions. Verify with the funder before applying.

What they actually fund

A grant that serves more than one cause is counted under each cause it fits, so the totals above can overlap — the headline grant count above is the true total.

Where their Florida grants land: West Palm Beach, Palm Beach Gardens, Deland, Tampa, Gainesville.
